RAIL-SECURING DEVICE.

SPECIFICATION forming part of Letters Patent NO. 779,061, dated January 3, 1905.

Application filed March 4:, 1904. Serial No. 196,603.

To all whmn it may concern:

Be it known that I, JOHN H. BARR, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented or discovered a certain new and useful Improvement in Rail-Securing Devices, of which improvement the following is a specification.

The invention described herein relates to certain improvements in means for securing rails to cross-ties, and has for its object the provision of a suitable bearing-plate for the rail, a rail-securing means which will not have any injurious action on the cross-tie, and a bearing outside of the flange of the rail for the head of the rail-securing device.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan view showing a portion of a rail and cross-tie and my improvements applied thereto. Fig. 2 is a sectional view on a plane indicated by the line II II, Fig. 1; and Fig. 3 is a view similar to Fig. 2, illustrating a modification of my improvement.

In the practice of my invention tie-plates 1, formed of steel or other suitable material, are interposed between the flange 2 of the rail and the cross-tie 3. In order to avoid the splitting of the tie incident to the use of spikes, I employ screws having suitable threads and provided with a head 4:, adapted to lap over the flange of the rail, as shown. In the use of these screws holes are bored by a suitable tool in the tie and the screw inserted by a wrench fitting the angular head 5. By thus boring a hole in the wood and inserting the screw as described the wood adjacent to the screw will not be injured or opened up to admit moisture.

In order to avoid any lateral strain on the portion of the screw adjacent to the head when the latter bears on the flange of the rail, bearing or supporting ribs 6 are formed on the tie-plate. As clearly shown in Fig. 2, these ribs are made of such a width and so arranged on the plates that a recess is formed between them for the flange of the rail. The upper surfaces of the outer portions of the ribs are inclined to correspond with the inclination of the upper surface of the flange of the rail, thereby forming two uniform bearings or supports for diametrically opposite portions of the heads 4. As shown in Fig. 3, one of the bearing-ribs, as 7, may be made independent of the plate, which is thereby adapted for use with rails varying as regards the width of the flange.-

I claim herein as my invention 1. A tie-plate for rails having in combination therewith ribs arranged along the plate a distance apart greater than the Width of the flange of the rail and adapted to form bearings for the outer portions of the heads of rail-securing screws, su bstantially as set forth.

my hand.

JOHN H. BARR.
